Table 2.

Total number and proportion of calves (%) that became viremic and shed virus in nasal secretions after challenge (days 0 to 28) with BVDV 2 1373 in each group

Group	Number of viremic¥ calves (%)	Number of viremic calves that shed virus (%)
A	11 (90)*	8 (72.7)*
B	2 (16.6)	0
C	3 (25)	0
D	6 (54.5)*	2 (33.3)

¥, viremic calves = calves with a BVDV positive sample in WBC or serum.

A higher proportion of control (A) and group D calves became viremic and shed virus after challenge compared with calves from groups B and C. The star *sign refers to statistical significance (P < 0.05).
